IMPROVEMENT IN FEEDING DEVICES FOR GRINDINGMILLS.

Specification forming part of Letters Patent No. 153,668, dated August4, 1874 g application iiled April 22, 1874.

To all whom it muy concern Be it known that I, GILES S. ORANSON, of thetown of Phelps, county of Ontario, State of New York, h ave invented anImprovement in Feeding Devices for Grinding-Mills, of which thefollowing is a specication:

The object of my invention is to provide an arrangement of mechanism forthe purpose of conveying that product in the manufacture of iourcommonly known as middlings7 in a uniform and constant quantity as fastas they are formed from the bolt to the eye7 of the mill, for thepurpose of grinding the same in connection with the Wheat.

Referring to the drawing belonging to this specication, E represents theend of an ordinary hour-bolt, from which extends the spout D, to conductthe middlings to an auxiliary conveyer, A, fastened to the mill-curb,and driven by a cord or belt from any convenient point. At the end ofthe auxiliary conveyor is a exible rubber tube, B, reaching down-as faras possible into the eye of the stone. The

object of this tube is to conduct the middlings and discharge them asnear as possible to the bottom of the stone, to prevent the accumulation of the same upon the sides of the eye,

'(being held there by centrifugal motion,) and as will be the case whenthey are discharged into the eye of the stone from a iixed Atube in aslantin g position, as is usually arranged. The middlings are in thismanner conveyed from the bolt to the eye of the stone, and fed to thesame in a uniform and constant quan! scribed.
